WILLIAM B. WESTBROOK, OF CLIFF, KENTUCKY.

CONCRETE RAILWAY-TIE.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application led November 20, 1907. Serial No. 403,022.

To all 'whom it may concern.:

Be it known that I, WILLIAM B. WEST- BRooii, a citizen of the United States, residing at Cliff, in the county of Floyd and State of Kentucky, have invented certain new and useful Improvements in Concrete Railway-Ties, of which the following is a specification.

This invention relates to railway ties, and especially to the class of cross-ties composed of concrete or similar plastic material.

The object of the invention is to provide, in a concrete railway cross-tie, novel and peculiar means for holding and bracing the concrete or similar plastic material, and for holding1 rail-seat blocks or chairs in such ties.

A further obj ect of the invention is to provide, in a concrete railway cross-tie having cavities or recesses for rail-blocks or chairs, a series of binding wires extending throughout the length of the ties and across the latter for the purpose of holding and bracing the concrete, and for forming a keeper for said blocks.

A still further object of the invention is to provide, in a concrete railway-tie having cavities or recesses therein for rail-blocks, a series of binding wires certain of which extend longitudinally within the walls of said recesses and across one end of the recesses where they engage such blocks to hold the latter in the recesses.

Other objects, advantages and improved results are attainable through and by the special construction and arrangement of the tie hereinafter more fully described and set up in the claims.

In the accompanying drawings forming part of this application :MFigure l is a perspective view of a railway cross-tie embodying this invention. Fig. 2 is a longitudinal section taken through one of the recesses, showing in dotted lines the block in removable position. Fig. 3 is an enlarged crosssection through one of the recesses with the rail-block or chair removed. Fig. 4 is a plan view of the core wires. Fig. 5 is a perspective view of one of the rail-blocks.

The same reference numerals denote the same parts throughout the several views of the drawings.

The concrete or other suitable plastic material of which the tie 1 is composed, is

formed about or built around a series of longitudinal rods or wires 2 extending throughout the length of the tie at intervals therein, and such wires are continued around within 'the ends of the tie to form crossbinders at each end of the tie. In molding or forming the tie, a recess 3 is made therein near each end thereof for the rail-block 4. The outer end of the recess 3 is beveled. The bottom of said recess extends into the body of the tie and the top of the tie over-hangs such inward extension so as to form a beveled lip 5, and a V or wedge shaped cavity 6 at the inner end of the recess. The side walls 7 of the recess have embedded therein a binding-wire 8, which crosses the cavity under the said lip to support the latter and to form a bearing or keeper 9 for the railblock 4. The block 4 is made to it the recess 3, and has a V or wedge shaped inner end formed by a beveled face 10, and a curved bearing 10a, to fit under the keeper 9, and into the cavity 6. The outer endV of the block 4 is curved or convexed and has a hole ll, for a suitable bolt 12 for securing the block in the recess and to the tie. This bolt may be separate from the tie, or it may be molded with it, but I prefer to apply the bolt as I do the blocks so that the bolt-holes of the blocks and in the tie may be made together and their position varied as desired or as occasion may demand.

It will be observed that the block-keeper protects the tie-lip from engagement by the block; that the block can not be displaced by vertical movement; and that in the swinging movement of the block, which is necessary to remove it, the keeper forms a pivot bearing against which the beveled face 10 works, while the bearing 10JL works against the bottom of the cavity.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. The combination with a railway crosstie having recesses each terminating in a cavity, and rail -blocks having a beveled face and iitting the recesses and the cavities, of the binding wires embedded in the side walls of the recesses lengthwise such walls and extending crosswise under the top wall of the cavities to support the top wall and to form a bearing for the said beveled face.
